Let x be the amount of winter snow that accumulates in the spring soil. The equation that represents the situation from the given above is,
x / 12 = w
where w is the depth of water. Substituting the given values,
x / 12 = 6
The value of x from the equation is 72. Therefore, the amount of winter snow is 72 inches. The answer is letter C.
3x−2y=12;−3x+8y=−6
Step: Solve3x−2y=12for x:
3x−2y=12
3x−2y+2y=12+2y(Add 2y to both sides)
3x=2y+12
